.AppIication filed J'uly 6,

This invention relates to smoke consumers.

An object of the invention is to provide an apparatus for passingcombustion products emitted by furnaces, kilns and the like through a spray lin the novel and eflicient manner hereinafter disclosed to remove the carbon and other obnoxious substances from the combustion products prior to its Adischarge into the open air.

Another object of the invention is to proliereindisclosed for washing the combustion products to. remove therefrom the heavy substances so that the products of combustion will be ultimately discharged without such elements and thus -freed from objectionable characteristics.

Other objects of a specific nature will appear from the following description, reference being made toy the drawings in which- Fig. 1 isa view with parts in section showing a satisfactory embodiment of the invention.

Fig. 10 is a view showing a gate or valve forming a part of the wa ter seal of the device which may be opened to permit removal of the floating substances removed from tlie combustion products.

Whilethe invention is. shown in connection with a kiln 1 for use in the manufacture of brick or fire clay products, the ins vention 'is not restricted lto use with such products but may be satisfactorily used in connection with other combustion apparatus.

As shown a pipe or fiue 2 from tie kiln 1 1 i925. serial No. 41,585.

extends loosely through a part 3 of the top wall ofthe'kiln and is capable of oscillation or inclination with the settling or chan e of position of any of the contents of the kiln which contact with the lower yend of said pipe or flue 2. The pipe or flue 2 is preferably provided with an opening in one side' (Figs. 1 and 5) which may be opened and closed byan air draft door 4 hinged to the pipe 4or-fiue and held in closed position by a releasable catch 5.

The upper end/of the ipe or fiue 2 extends through the wall oi) and into a pipe 6 surrounded bya flange .8 extending into the pipe 6 and having its inner extremity -flared away from the pipe or flue 2, per- `6 will be subjected to the action of the sprays from said nozzles and a considerable portion of the obnoxious substances, such as carbon, will be washed and removed from the combustion products.

From the pipe 6 vthe combustion products are discharged into an enclosure 10 preferably through the top wall number of water pipes 11 extend into-.the enclosure 10,1certain of said pipes 11 having upwardly directed spray nozzles 12, and an-` other of said pipes 11 havin downwardly directed spray nozzles 13. The spray nozzles 12 and 13 are preferably arranged in series, two series of said nozzles being separated by a downwardly extending partition 14, and other series of said spray nozzles being separated by an upwardly extending partition 15. T he .partition 14 terminates above the bottom of the enclosure 10 so that passes downwardly in the space between the partition 14 and onewall of the enclosure 10,

during `such movement being subjected to the action of the sprays in said space; and thence under the lower end of the partition 14 and upwardly through the spacel between the partitions 14 and 15 in which space the iio '- combustion products thereto. The lower `end of the artition 14 is preferabl procombustion products is subjected to sprays in said s ace, and from said last namedI s ace over tV e u per end of the artltlon 15 into the space getweemthe artition 15 and the ,adjacent wall of the enc osure 10; and thence downwardly in said last named space throuh the sprays thereinto an outlet ipe 16 whlc in the embodiment shown 1n 1g. 1, 1s connected with an airpump or Yfan 17 rfunctioning to maintain continuous movement of the vided with iverg'in baiiies 18 whic tend to deflect and cause t ev combustion products to pass through and be subjected to the action of the sprays. Similarly, the wall'of .the Aenclosure 10 hasa baille 19' adjacent to the opening into the pipe 16 and functionin to preventformation of a streamzo'rfreduce current of combustion products to said pipe 416'; .all with the .result that the combustion v moved.y The downwardly extending products are properly subjected to the action of the sprays. 1

From fthe fan'or air pump 17 the fumes withdrawn from the enclosure 10 are discharged through a'pipe 20, and wherever needed or required said pipe 20 may discharge'into an additional enclosure 21 having a, tortuous passage formed by an upwardly extendin wall 22 terminating short of the top wall o? the enclosure, and a downwardly extending wall 23 terminating above the bottom of the enclosure. Pipes 24 extend into the enclosure 21, certain of which pipes are equipped with upwardl directed spray nozzles 25 and another of w ich pipes 1s equippedwith downwardly directed spray `nozzles 26, 'so that as the combustion prod-A ucts vor fumes -pass through the. tortuous` passageas indicated by the arrows, they are subjected to the action ofthe sprays andA the remaining obnoxious elements are reartition'23 has diverging baiiies 27 near its lbwer end',v causing the combustionIV products to be r subjected satisfactorily to the action of the sprays. From the end of the tortuous passage in the enclosure'21V thev clarified smoke is discharged through an outlet pipe 'or flue 28, adjacent "to the opening into which a baiiie 29 is provided top'insure proper move-v ment of the smoke through the sprays.

v inner .walls 32 of said basins converge up! The side walls of each of the enclosures 10 and 21 terminate in basins comprising vertical outer walls 30 having their ends connected to extensions 31. of the end walls of the enclosures 10 and 2l, respectively. The

wardly and inwardl to intersection forming a longitudinal ivider 33, causing the spray deposits to pass in approximately `equ'al proportions to the two ,side basins.

An outlet or overow pipe 34 is provided for each vside basin and open therefrom above the planes of the lower ends ofthe side walls of the enclosures 10 and 21,l so that the lower ends of saidI side walls are immersed in water which vprovides a seal. Drain `pipes 35 open near the bottoms of the basins for draining olf the contents thereof and areI equipped .with valves 36. Screens 37 connect the basin walls 30 with the lower portions of the side walls of the enclosures 10 and 21, respectively, toprevent the accumulation of deposit from the outside into said basin.

Figs. 6 and 7, the side walls of the spray enclosures 38 which corresponds to either of the enclosures 10 or 21 have their inner sides provided with vertical corrugations'39 which increase the inner surface area of the j walls providing wet surfaces of larger area, to the action of which the assin combustion products is subjected. n ad ition, the vertical partitions 40, corresponding tothe vertical partitions shown in Fig. 1, the enclosure 38 has within the -tortuous assage formed b walls of t e enclosure, a number of baiiies 4l inclining inwardly and downwardly from the side walls of the enclosure, one series of said partitions and by t e end In the alternative structures :shown in such baiiies near the top and another'series of the drawings. l

Fig. 8 shows an alternative form of connection from the kiln or furnace with a spray pipe 46 corresponding to the spray pipe 6 previously described. As shown ation 51 opening into the pipe 46. The lower end of the pipe 50 is imbedded in granular or pulverized material 52` in a basin 53 formed around the outlet 49. 4The pipe 50 yis rovided with a damper 54.

` s shown in Fig. 8 there are series of pipes 50 opening into opposite sides of the spray pipe 46and serving adjacent series or rows of kilns. A water 'pipe 55 corresponding to the water pipe 7 extends through the pipe 46 and has sprayk nozzles 56 in connection therewith. 7

A water pump l57 of any appropriate commercial construction may bezused" to force water through the water pipes and through the spray nozzles to produce the sprays. If

desired a single motor 58 may have its shaft In addi-l ldentical with parts indicated by the same reference numerals in the preceding views As shown, the an device 17 may be used towithdraw the combustion products from the tortuous passage in the enclosure and to discharge the remnants of the combustion t products into the tortuous passage in the spray pipe opens,

enclosure 21, and the water pump 57 may be used to 'force water through all of the spray devices embodied in the apparatus, a single motor serving to operate both the fan and the water pum l As shown in Fig. 1 0 the water seal at the lower edges of the side walls ofthe enclosures may comprise a gate orvalve 60 which is capable of vertical sliding movements and which, in its lower osition, has its lower edge immersed in t e water. When the gate or valve 60 is raised access may be had to the interior of-the enclosure'through the elongated opening 61, permitting the floating substances to be skimmed off, while-the settlings may be withdrawn throughthe pipe 35.
